Even before Dobbs/Trump Democrats did much better with women compared to the GOP: Why?

[Libertas Vel Mors]

Not sure why the biological explanation is getting so much hate here. Economic differences certainly play a role in the gender divide, but don't explain why the divide persists even for men and women with similar incomes, industries, and educations. Seems very likely that at least one reason for the gender divide is biological.

As for why women used to be more right wing than men, a potential explanations could be that
that women are more likely to value stability, but men are more sympathetic to conservative ideological appeals. Thus, female voters might like a candidate like Eisenhower more than male voters, but be less likely than male voters to like a candidate like Reagan. A good example of this would be Chile, where women were more right wing up until the 2021 election, where Kast, a more ideologically conservative nominee than past candidates, performed better among men than woman.
